# Backdrop

Aggiunga overlay di caricamento alle app PowerShell Universal con New-UDBackdrop, visualizzando contenuti personalizzati e chiudendo il backdrop con un handler OnClick.

Il componente backdrop posiziona un overlay sopra l'intera pagina. È utile per visualizzare gli stati di caricamento.

## Backdrop di base

Per creare un backdrop di base, può utilizzare il cmdlet `New-UDBackdrop` e includere il contenuto da mostrare all'interno del backdrop. Il contenuto sarà centrato nella pagina. Per mostrare il backdrop, utilizzi il parametro switch `-Open`.

```powershell
New-UDBackdrop -Content {
    New-UDTypography -Text "Loading..." -Variant h2
} -Open
```

## Handler OnClick

Il backdrop fornisce un handler `-OnClick` che può utilizzare per chiudere il backdrop quando viene cliccato. Può utilizzare `Set-UDElement` per aprire e chiudere il backdrop.

```powershell
New-UDBackdrop -Id 'backdrop' -Content {
    New-UDTypography -Text "Loading..." -Variant h2
} -Open -OnClick {
    Set-UDElement -Id 'backdrop' -Properties @{
        open = $false
    }
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.devolutions.net/powershell-universal/it/app/components/feedback/backdrop.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
